Bash and Nick were great!
Bash and Nick were great! Bash was patient and really worked hard to make sure we were not pressured and that we were getting the car that would be best for us. We got a 2024 Buick Envista and are so happy with the whole experience

How easy it is to work with Johnson Auto Plaza.
Purchasing my new 2022 GMC Sierra was easy as buying something through the drive-thru. The salesperson, Chris Maneotis was awesome. He explained how my trade-in would go towards the purchase of the new truck and went over the financing and options. I would highly recommend anyone to work with Johnson Auto Plaza.
